Need some Haskell programs

Hello Sir, I am a computer science tutor, I teach (among others) Haskell, Prolog and Algorithms. I have done many projects like this, and I'm one of the top Haskell developers, and you can check by clicking on my profile picture. Please contact me for more details when possible. I look forward to work for you, Sir. Best Regards.

I program in Haskell in my spare time, I think I can face these problems. Just a question about what are the other "more complex problems"?
